Radio reception Very poor reception from the digital tuner. Trouble receiving most of the strong local stations even after "optimizing" antenna placement.

How "local" is local?

Are you using an out door antenna? Digital signals are weak and fragile. Leaves on a tree between your antenna and transmitter can cause hassles. They are not brutal like the older analog signals of yore.

Now if you have a good outdoor antenna and local stations and you still have hassles, then the problem lies with the tuner section of your set. With analog signals, the weaker the signal the more noise in your picture. Digital does not work that way. It either works fine or you get nada. No snow but no in between reception either.

Do you have the BLUE power antenna wire hooked up?

If not it may help your issue

I had the same exact problem. Toyota changed the Amolifier that improved sound quality but not the FM Reception.

THE HARNESSES CONNECTING ANTENNA TO RECEIVER (TWO OF THEM) HAD IAASUES. REPACING THEM FIXD THE ISSUE. FM RECEPTION EXCELLENT NOW !!!!!!!

Unless this a new TV with ATSC (digital) tuning built in, you will need a digital adapter for off-the-air reception. Older TV sets have analog tuners, and analog broadcasting ended in June 2009. Wal-Mart and Radio Shack carry the adapters, as do other retailers. Your antenna connects to the adapter, and the adapter sends the converted signal to the TV on channel 3 or 4.

With digital broadcasting, a strong signal is necessary. Unlike the analog days, when a weak signal just meant a fuzzy picture, a weak digital signal will cause pixellation (blockiness) or freezing of the picture, or may not even be detected by the tuner. Depending on how far you are from the station's transmitter, you may find that rabbit-ears may not work too well. You may need an amplified antenna or even one outside to get best performance.

Do you use an indoor antenna ? Nowadays, with all gear around, like micro-waves receptors, strong motors, satellites, etc., reception becomes quite poor, unless you use an external antenna, properly set to catch broadcast stations. FM reception particularly has its signal much improved in that way. Correct demodulation requires a good an somewhat large outdoor antenna. Hope I could help. Good Luck.

This usually means that the tuner is not getting sufficient reception for the station you are trying to listen to.

Receivers come with cheap wire loop antennas try upgrading to a powered FM antenna available online or at your local Radio Shack.

Hope that helps

I don't know in what area you live & therefore how strong your reception area will be, but as a general rule an indoor antenna is never the best type of aerial to have to receive digital signals, you will always find that you pick up some good strong channels but more often the rest of the channels will be poor or non-existant & will constantly break-up/freeze etc. The best advice would be to try & fit an outdoor antenna if possible.

Check antenna connections at radio and antenna assy.. Poor connections will only receive AM and hardly any FM

You may have a bad antenna or antenna cable.
FM signals are measured in microvolts and are easily influenced by poor antennas or a mashed antenna cable.

Turn on the radio and turn the AM/SW BAND switch to the AM position. MW appears in the display. Use the outer ‘fast’ tuning knob to find stations, fine tuning with the inner ‘slow’ knob
when needed.

• If there is interference from adjacent stations, place the BAND WIDTH control in the NARROW position. If there is no interference, leave it in the WIDE position.

• If there is excess background noise, turn on
the SW LPF switch, which may minimize the noise.

• If a station is so strong that audio distortion occurs, reduce the gain level with the AM/SW RF GAIN control knob by turning it counterclockwise.

• The telescopic antenna does not have to be extended for AM reception. The radio has an internal, directional, ferrite-bar antenna for AM reception.

• To optimize AM reception, swivel the radio until maximum signal strength is achieved.

All of that being said: It's very tough nowadays to receive AM in this 2008 electronic world. If your able install a longwire SW antenna outside, and have access to a good earth ground, you can boost the AM signals and beat the noise being generated all around you.
